2Diagnosis Coding Guidelines For Radiology Billing
- Submitting a clean claim and bringing accurate
reimbursement for radiology is a challenging task
requiring billing and coding expertise. Although
many claims are being paid when initially
submitted, post-payment reviews by insurance
carriers might result in returning the insurance
reimbursements. All this can be avoided with
proper documentation supporting medical
necessity. With radiology services coming under
intense scrutiny for medical necessity, it is
more important than ever to ensure documentation
supporting medical necessity. This includes
ensuring that diagnosis coding is done in
accordance with the official coding guidelines
and the Center for Medicare Medicare Services
(CMS) policy. Following diagnosis coding
guidelines will support medical necessity
ensuring insurance reimbursements while billing
for radiology services. - Diagnostic Test Order
- An encounter for radiology services begins with a
test order from the referring (ordering
physician) which is then taken to an imaging
center, hospital, or another provider of
diagnostic imaging services. A complete and
accurate test order is crucial to coding
compliance because payment for services by
Medicare is made only for those services that are
reasonable and necessary. Furthermore, CMS
charges the referring physician with the
responsibility of documenting medical necessity
as part of the Medicare Conditions of
Participation (42 CFR 410.32). - The Balanced Budget Act of 1997 reiterates the
above requirement in Section 4317(b) where it
states that the ordering physician must provide
signs/symptoms or a reason for performing the
test at the time it is ordered. If the referring
physician indicates a rule out, he/she must
also include signs/symptoms prompting the exam
for ruling out that condition.

- In the event this information is missing, the
ordering physician should be contacted for this
information before proceeding with the exam. - Since medical necessity is determined by those
signs/symptoms provided by the ordering
physician, it is vital to have this information
at the time of final coding even when the
radiology report identifies an abnormal finding
or condition. This information is key in helping
to determine whether or not a finding is
incidental or related to the presenting
signs/symptoms. - Furthermore, a test ordered to rule out a
specific condition is considered a screening exam
in the eyes of Medicare and would need to be
coded as such in the absence of documented
signs/symptoms, with a screening code assigned as
the primary diagnosis and any findings assigned
as additional diagnoses. - Choosing the Primary Diagnosis
- As per ICD-10-CM official guidelines, for
patients receiving diagnostic services only
during an encounter/visit, sequence first the
diagnosis, condition, problem, or other reason
for encounter/visit shown in the medical record
to be chiefly responsible for the outpatient
services provided during the encounter/visit.
Codes for other diagnoses (e.g., chronic
conditions) may be sequenced as additional
diagnoses. For encounters for routine
laboratory/radiology testing in the absence of
any signs, symptoms, or associated diagnosis,
assign Z01.89.

If routine testing is performed during the same
encounter as a test to evaluate a sign, symptom,
or diagnosis, it is appropriate to assign both
the Z code and the code describing the reason for
the non-routine test. For outpatient encounters
for diagnostic tests that have been interpreted
by a physician, and the final report is available
at the time of coding, code any confirmed or
definitive diagnosis(es) documented in the
interpretation. Do not code related signs and
symptoms as additional diagnoses. Radiology
Report While the test order may determine medical
necessity and initially drive the encounter, a
review of the final radiology report holds the
key to determining the correct diagnosis codes
for an encounter. Radiology reports should
contain four main sections clinical indications
technique summary of findings and impression
and final interpretation. The clinical
indications listed on the report should be those
signs or symptoms provided by the referring
physician that prompted the ordering of the test.
The radiologists final interpretation, the
impression, may list multiple conditions and is
the final piece of the puzzle in choosing a
primary diagnosis code. Additionally, a careful
review of the clinical indications will help
determine whether or not certain conditions
mentioned in the findings section, or in the
impression, are clinically significant or simply
incidental findings.

- Documentation for Diagnosis Code
- At first glance it may appear that diagnosis
coding for diagnostic radiology exams is
straightforward, it actually can be quite
challenging. In many cases, the documentation
that must be reviewed prior to assigning a
diagnosis code may be unavailable, unclear, or
contradictory. There are two key documents for
review. Although each is a viable source document
for selecting a diagnosis code for the encounter,
utilizing only one of these two documents to
select procedure and diagnosis codes can result
in unnecessary coding compliance risks for any
provider of services. - Test order with accompanying signs/symptoms
- Radiology report containing the final written
interpretation - Accurate selection of diagnosis codes and
following coding guidelines will ensure steady
insurance reimbursements in radiology billing. If
